T 0 all whom it may concern:

Be it known that we, SnI1CH1Ro SENGA, IWANE KAWATA, and Rroror-rr NAITO, subjects of the Empire of Japan, residents, re-

a knob on the silk strand.

spectively, in care of business department of Kanegafuchi Boseki Kabushiki Kwaisha, I-ligashi-Shiri-Ike, Kobe, Japan, have invented certain new and useful Improvements in Filament Suppliers for Silk-Reeling Machines, of which the following is a specification.

Our invention relates to improvements in filament suppliers for silk reeling machines, and has for its object to supply filaments to the silk reeling machine perfectly and easily.

' The improved filament supplier comprises a main wheel provided with cuts or openings leading to the centre and forming special teeth around said wheel, and a preparatory wheel having saw-like teeth around its periphery and situated closely above said main wheel so that part of its periphery overlaps part of the periphery of said main wheel, both wheels revolving in the same direction, The filament of a cocoon dropped beside the supplier is first caught at one of the teeth of the preparatory wheel which is running and further transferred to one of the teeth of the main wheel revolving In those filament suppliers hitherto in use in silk reeling machines a filament is supplied by holding it on the operators fingers and feeding it to the periphery of the supplier through the opening of the .former. The operation of said feeding needs much skill and as the useless end of the filament can not be cut off entirely it is apt to form Besides in case the filament is not cut in time it twines around the silk strand while being reeled and often forms screw-like knobs on the silk strand.

According to the present invention the operation of supplyingfilaments is performed entirely mechanically by merely dropping a cocoon, with its filament unloosed, beside the supplier and needs no skill for feeding a filament. As the useless part of the filament is'a-utomatically cut at the time of i:

supply the formation of knobs is quite avoided and filaments can be supplied to the silk reeling machineinstantly and perfectly. The, production of raw silk is therefore accelerated and its quality is remarkably improved. v I

The accompanying drawing shows an example of the improved filament supplier. Fig. 1 is an elevation showing the operation of supplying a filament. Fig. 2 is a plan view of same. v Referring to the drawing represents a main. wheel of the supplier. Itis made of a thin metal plate and provides curved cuts or openings (2) leading to the centre and forming special teeth (3) between them around the wheel. Said'wheel is'fixed at the lower end of a sleeve (4) and at the upperend of the sleeve a groovedpulley (5) is attached. The sleeve (t) is loosely fitted on a vertical axle (6) fixed at one arm of a forked frame (.7). The axle (6) provides a fine hole (8) at its centre and filaments are reeled upwards through said hole as in an ordinary silk reeling machine. (9) represents a preparatory wheel, larger in diameter than the main wheel (2) and having saw like teeth 10) on its periphery as shown. It is also made of a thin metal plate and its sleeve (11) provided at its upper end with a grooved pulley (12) is loose ly fitted on a vertical axle (18) fixed at the other arm of the forked frame (7 The preparatory wheel (9) is situated closely near above the main wheel (1) and overlaps with the latter at a part of the periphery as shown and the wheels (1) and (9) are revolved in the same direction as shown with arrows (a) and (b) in Fig. 2 by the grooved pulleys (5) and (12) and any other suitable driving means.

)Vhen it is wanted to supply a filament to i the silk reeling machine, a cocoon with its filament unloosed and held above is dropped aside the preparatorywheel (9) into the reeling basin as shown in (0) with dotted lines in Fig. 1. The filament is first caught by one of the teeth (10) of the preparatory wheel (9) and after moving in the direction of (b) about half a revolution of the wheel (9) said filament is further caught by one of the teeth of the main wheel (1) at the overlapping part of both wheels as shown in (cl) in Fig. 1 and while the main wheel revolves in the direction of (a) as shown the filament is taken towards the centre of the main wheel (1) through the opening (2)v and is united with other filaments 0 being reeled. 1 The filament of the supplied cocoon is not cut by the teeth of the wheels 1 and 9 until said filament comes in contact with other filaments in the course of reeling for the reason that the dropped cocoon freely floats in the reeling basin and the filament thereof is loosened during movement of the wheels. After the filament (Z has been brought into contact and united with the filaments forward rotation of thewheels 1' and 9 increases tension on the filament and the latter is finally out at its upper portion by said wheels, the portion of the-filament lying below the wheels being reeled upwardly with the other filaments c. The edges of the openings, or recesses 2 in the main wheel 1 are smoothly finished to insure free sliding movement of" the filament therover during its movement toward the center of said wheel and'before said filament is brought to the breaking tension.

We claim A'filamen-t supplier for silk reeling machines cornprising a main wheel a shaft sup: porting said wheel-having an ope-ning there through adapted to receive filaments of coof the second mentioned wheel being adapted to engage and guide the filament of a cocoon into the path of oppositely moving teeth of the first mentioned wheel and said latter teeth being adapted to cause the fila ment. to be guided into contact and united with filaments passing upwardly through the opening in said shaft, said filament being broken due to increased tension thereon incident to further movement of thewheels. In testimony whereof we have afiixed our signatures in presence of .two witnesses.
